Specification of Letters Patent.

Application filed August 24. 1915. Serial No. 47.125.

To all whom it may concern lBe it known that I, At'ct's'ris H.v SEARS, acitizen of the. I nited States. residing at Greensboro, inthe county ofGuilford and State of orth Carolina. have invented new and usefulImprovements in Egg-Heaters, of l which the following is aspecification. This invention relates to improvements in egg beaters,the Aobject-'olf 'the invention being toV provide an improved device ofthi-s character which is especially adapted for use in beating eggs andin mixing liquids and otherlike purposes, and which is' simple inconstruction. is strong and durable and 1n wliichfthe beating elementisrevolublein reverse directions and isalso moved upwardly anddownwardlyy when in operation to thoroughly agitate and beat the4 eggs for other material.

'The invention consists in the construction, combination -andarrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings :-Figure1 is a vertical sectional'view ofan egg -beater yconstructed injaccordance withmy invention.. Fig. Q'is avertical sectional view of the same on the plane at right angles to thatof Fig. 1. Fig. 31s a horizontal sectional a view of the same'on theplane indicated by the line a-a'of Fig. 1. Figs., are detail views.

" comprises an upper member 10 and a lower In the embodiment of myinvention I provide a frame 1 which is here shown as comprising acircular bottom 2, a circular top 3 y and vvertical rods 4 which connectthe top. and bottom. The bottom comprises a ypair of members 5 6, thecross bars 7-8 of which are at right anglesto each other, theupper crossbar 7' having' acentral bearingopening 9 which is closed on the lowerside by the .cross bar 8. The top 3 of the'frame member 11 spaced a'suitable distance therefrom, each of said members having a centralbearing opening.' l l l j A vertically arranged shaft 12 has its lowerend stepped in the bearing and its upper portion mounted in the bearingsin the center of the .members 10--11'of the top and is provided at a`point between' said meinbers with apinion 13. The shaft has reverselyarranged screw threads 14, which 'extendrom near the upper end to nearthe lower end of saidshaft.

A shifting' bar 15 comprises upper and lower members 16-17 which "areconnected together at their-ends by tubular guides 1S whichoperatefoiirtwo of the rods Je of the frame s o -that said shiftingbearing is. mounted for vertical reciprocating move# ment. i

A beater element 19 is providedl which .comprises 'a hub 20' andradially arranged wings :21. The hub is slidable vertically on the shaftand has a set screw :22v to engage when turned Vfirst in one .directionand then 4 in therevers'e direction -causes- 'the' beat-er v elementtorotate therewith butat a'lowerl rate of speed, owing to the retardingresistance of the materials'and the screw or point 22 'coacts with the1reversely arranged screw threads of the shaft to move the shifting barand also the beater element up vand down in the frame and thereby causethe beater element to the "more thoroughly beat, agitate and stir the'eggs or other materiah Patented June 6, 1916. v

the cross bar of the upper member 10 of the frame.4 A stub shaft 26projects from' one side of the handle Q3 and 'forms the bearing for agear wheel27 which engages' the pinion 13 and. is provided with' a crankhandle 2S whereby said gear wheel may be turned in reverse.l directions,land caused to coperate with. the pinion and therebyimpart-the requiredreverse rotary movements l 9ovv to the shaft.
